I solve the problem doing this:
1.insert one working sim card (the phone currently locked to) sim,
Enter *7465625*228#
*7465625*28638#
wait until phone reboot ,wait until you can see the reception bars.
2.turn off and insert one (Non-working sim) ,turn on it ,should show "wrong card"
again.
enter#7465625*228#
3.turn off the phone, switch (change )to working sim,enter
*7465625*77*99999999*99999999#
#7465625*77*99999999#
4.off the phone again ,insert non-working sim
enter*7465625*638*00000000*00000000#
enter#7465625*638*00000000#
phone unlocked....
I've try it with one T219S, and works.
